Do you have virus and Spyware protection? If you are running Windows XP, I suggest running a System Restoration. To do this, follow these steps... Click on Start -> All Programs -> Accessories -> System Tools -> System restore. A new window will now appear. Make sure "restore my system to an earlier time" has a bullet point next to it, and click on the next button. You will now see a calendar. Click on the day of, or the day before he changed any settings. If applicable, make sure the TIME on that day is before he messed with any settings. Click on the date and time so that it is hilighted, and click on the next button. You will now see a confirmation screen. Make sure the date and time is correct, and click on the finish button. Your computer will now restart. Before it "saves your user settings" you will see a little status box. It may move rather slowly, so be patient. Once the system runs its course, the computer will restart. Login as usual, and see if your settings are back to normal. Hope this helps
